Нефтеперекачивающих полированного штока BOP

The oil-pumping polished rod blow-out preventer A.Uses and characteristics: The oil-pumping polished rod BOP is a piece of safety sealing device for plugging the cavity of the pipeline in the process of oil-field exploitation. In the operation process of pumping unit, by manual control or hydraulic control, our product can not only seal the oil-pumping polished-rod, but also enclose the space between the oil-pumping polished-rod and the pipeline, in order to realize the aim of safe production and environmental protection. This producthas lotsof advantages likereasonable pressure distribution, compact structure, light weight and small size, and it can bear large pressure.
